1987 FJ1200 - new project

[MarioR]

Hi Guys,

Another beautiful day, just got another Fj1200. This one is 87 US model.
A few goodies that came on the bike:
1. Full supertrap exhaust
2. Upgraded oil cooler kit
3. Front forks brace
4. Corbin solo seat
5. Rear wheel custom fender
6. Lockhart front fairing
7. Braided brake and clutch lines
8. Custom front and back foot pegs that moved pegs to the back. This is first thing that will go back to stock. Very uncomfortable to ride like this, kind of racing set up.
9. New battery
10 Gas tank new cap

Rest is pretty much stock and will require some kind of restoration.


So far there is a long list of fixing stuff:
1.  Carbs completely disaster, dirty and not set up properly every possible way - took it apart, cleaned up and adjusted. Probably will need proper main and pilot jets. Someone installed 135 main jetting....... so since I have KN filters and supertrap, will go with 42.5/117.5-120 jetting. This should be fine set up.
2.  Engine leaking I am assuming from oil filter and drain plug - to be fixed. I may install spin oil adapter.
3.  Try to run it when picked up but it has some issues like carbs and smoking from the pipe. So I did compression test and this is the result:
#1 - 120, #2 - 90, #3 - 110, #4 - 115
Not the greatest news but will work it out. That being said high possibility that rings are seized up. Will do leak down test later on and make a decision, what to do next. May try seafoam and Yama lube ring free to see if anything is changing.
4. Chain and sprockets are old and rusted so they will need to go and replaced with 17/41 - 530 ZVM-X Chain.
5. Tires are old so new to be ordered. Depending on what set I will keep.
6. Clutch slave is okay, working and not leaking condition.
7. Battery is new so this is bonus.
8. New plugs picked up, old one just old but they burned pretty even across. So this is the reason I think bike was sitting long time and rings are stuck. Will see.
9. Bar grips will need to be purchased - what you guys recommend?
10. Gas tank is disaster - it will need to be cleaned up. Will do vinegar and acid back and forth with some small nuts to clean most of the build up. Gas tank paint is good so I will try to recover it. If you guys have any better idea, please let me know 
11. Front forks seals are good and they have bracing. So no leaks, springs works okay.
12. Back shock is okay if I can say that.

Regarding wheels and suspension, here are my options:
1. Keep it stock and change bearing and tires, call it a day
2. Collecting parts for 92 USD front swap with back Thunderace full arm suspension. This will be very tempting....

Some cracks on the upper black plastic fairings that have to be fixed. Have two additional gauges - one temp gauge that doesn't work, other one unknown since doesn't work and blacked out. Will need to find some replacement or eliminated and changes or fix plastics.

Here is bike condition:

Check your valve clearances. You might have a tight valve.

Yes Pat. This is on the list for the next step to check. Thank you
